SPECIFICATION forming part of Letters Patent No. 729,250, dated May 26, 1903. Application ilcd October 28, 1902. Serial No. 129,175. (No model.)-

lb [tu whom, it muy; concern:

Be it known that l, ALFRED YOUNG, a citizen ofthe United States, residing at Boyce Station, in the county of Allegheny and State -of Pennsylvania, have invented a new and' useful Engineers Torch, of which the following is a specification.

This invention relates to torches employed by engineers, firemen,and other similar Workmen when oiling machinery at night or in dark places at other-times, and has for its ob? ject the production of a simply-constructed and convenient implement which may be extended longitudinally When required to increase its length and which may be readily collapsed when required; and the invention consists'in a casing provided with an inwardlyoperating valve adapted to be manually actuated from the exterior of the casing and the torch member proper teleseopically connected to the casing in position to be extended therefrom and provided with a packing means, whereby the pressure of the air wit-hin the casing will serve to support the torch member in its distended position.

Other novel features of the invention will appear in the annexed description and be specified in the claims following.

In the drawings illustrative ot' the invention, in which like designating characters are employed to denote ccrrespondingr parts in the different figures, Figure l is a side elevation with the device collapsed or inits shortest condition. Fig. 2 is a vertical sectional elevation with the device partially distended. Fig. 3 is a transverse section on theline III III of Fig. 2.

Y The outer casing is represented at 10, preferably in cylindrical form and of any suitable size, and Will preferably be of relatively thin metal and provided with a base member 11, having a depending.;r flange l2, by which a cavity 13 is formed in the base member opening outwardly, as shown in Fig. 2. A valve will be located in the closed end of the cylinder 10, preferably in the base member, and opening inwardly, the valve being indicated at 14 and provided with a stem l5, extending into the cavity 13, so that the valve may he manually opened by pressing upwardly upon its stem. It will be noted that the stem 15 does not extend to a point in ali .armut with the outer edge of the flange l2, so that when the device is set upon its base the stem l5 will notl come in contact or be affected by the support upon which the device rests. The flange 12 thus serves as a protection to the valve when the torch is placed in an upright position, as will be obvious.

The torch proper consists of a reservoir 16 for the oil, (indicated at 17,) with the wicktube 18, of the ordinary construction, located in its outer preferably conical end and supporting the wick 19 in the usual manner. The reservoir 16 will correspond substantially to the interior ot' the casing 10 and will slide freely therein and will be provided upon its inner end with a suitable packing 20, engaging the interior of the casing and shutting off communication between the inner portion ofthe casing and its outer end. By this const ruction'it will be obvious that when the torch member is drawn outwardly the packing 2O will prevent the entrance of the outside air between the two members 10 16 and will thereby create a partial Vacuum in the casing, which will immediately be destroyed by the opening of the valve 14 filling the casing with air and forming a support for the torch member and holding it in its distended position so long as desired. By this means the torch may be extended to any desired extent within the range of the casing 10, which is a veryconvenientprovision'in implements oi this character.

It will be obvious that the torch may be extended and supported by the air-cushion at any desired intermediate point within the casing 10 or extended to its full distance, as circumstances may require.

When the torch is to be collapsed, the simlength desired and without altecting the light ICO imparted by the wick 19, as the movement of the torch member 1b' longitudinally of the casing lO in no manner aects its light-giving qualities.

The device may be formed of any desired size and is thus adaptable to all the uses to which similar devices areput.

The parts may be modied in minor particulars without departing from the principle of the invention or sacrificing any of its advantages.

To prevent the reservoir portion 16 from being accidentally disconnected from the cylindrical portion l0 a wire or other frictionring 2l will be arranged in the upper rim 0f the member IO, as shown in Fig. 2.

Having thus described the invention, what is claimed isl. In a device of the class described, the combination with an outer casing, of a torch member slidably mounted therein and provided wilh an oil-reservoir and wick-tube, a packing carried by the torch member and bearing upon the inner Walls of the casing, and an inwardly-opening valve for controll ling the admission of airinto the casing, said valve being automatically operable by the outward movement of the torch member to admit air into the casing.

2. In a device of the class described, the combination with a casing having an opening formed at its lower end, of a torch member slidably mounted Within the casing and provided with an oil-reservoir and wick-tube, a packing carried by the torch member and bearing upon the inner walls of the casing, aninwardly-opening valve mounted over the opening in the casing, said valve being automatically operable by the withdrawal of the torch member for admitting air to the interior of the casing, and means carried by the valve and operable by hand for actuating the valve to permit escape of air from the casing.

3. In a device of the character' described, a casing having a base member provided with an exterior depression, an inwardly-operating valve located in said base member within said depression, and a torch member slidably disposed within said casing, substantially as described.

4. In a device ot' the character described, the combination of an inclosing casing, a'base member supporting said casing and having a depending flange forming an exterior cavlty to the base member, a valve in said base member and opening into said cavity, and a torch member slidably disposed within said casing and adapted to be extended therefrom, awicktube connected into said torch member, and a packing between said torch member and casing, substantially as described.

5. In a device of the class described, a tubular casing, a base member connected to one end of said casing and forming a closure thereto and having a depending flange whereby an outwardly-opening cavity is formed within the base member, a valve within the hase member and operative from within said cavity, and a torch member slidably disposed within said casing and adapted to be extended through the open end thereof, substantially as described.

6. In a device of the character described, a tubular casing, a base member connected to said casing and forming a closure thereto and having a depending ange whereby an ontwardly-opening cavity is formed Within the base member, a valve within the base member and operative from within said cavity, a torch member slidably disposed within said casing and adapted to be extended through the open end thereof, and a packing means between the torch member and casing, substantiall y as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ALFRED K. YOUNG.
